Extended Data Fig. 6: Posterior predictive distributions.
From: Global status and conservation potential of reef sharks
a, b, Distributions (blue) are shown for the full model, which had the majority (77%) of posterior model weight, of observed MaxN (vertical red lines) for 25 (of >15,000) randomly selected BRUVS sets from Global FinPrint (a) and the observed overall mean MaxN (vertical blue line) (b). Distributions that consistently overlap observed values are taken as evidence that the full ZINB model is consistent with the observed data. c, Frequency distribution of posterior predictive densities (box plots) and observed mean MaxN values (red dots) for 15,176 BRUVS sets observed as part of Global FinPrint. Note, in a, only 4.3% of observations were outside their 95% highest posterior predictive density, suggesting that there is no evidence that the full model is inconsistent with the observed data. Note, the plot in c was truncated at MaxN = 10 (representing >99% of observed MaxN) for clarity.
